From 57f3986231bb2c69a55ccab1d2b30a00818027ac Mon Sep 17 00:00:00 2001 From: jbrunet Date: Mon, 19 Dec 2016 16:05:37 +0100 Subject: [PATCH] net: phy: use boolean dt properties for eee broken modes The patches regarding eee-broken-modes was merged before all people involved could find an agreement on the best way to move forward. While we agreed on having a DT property to mark particular modes as broken, the value used for eee-broken-modes mapped the phy register in very direct way. Because of this, the concern is that it could be used to implement configuration policies instead of describing a broken HW. In the end, having a boolean property for each mode seems to be preferred over one bit field value mapping the register (too) directly.
